"The Tigers have traded pitcher Charlie Furbush, Triple-A outfielder Casper Wells, Double-A third baseman Francisco Martinez and a player to be named later to the Seattle Mariners for starter Doug Fister and reliever David Pauley.

Fister, a 27-year-old right-hander, is 3-12 this season with a 3.33 ERA but has an impressive WHIP at 1.17. He struck out 89 batters with Seattle this season, while surrendering 139 hits and 32 walks. Fister is tied for seventh among all American League pitchers with 2.0 walks per nine innings.

"His record is misleading," Tigers president Dave Dombrowski said today. "He has the lowest run support in major-league baseball."

And it's not even close. Fister's run support is 1.97 per nine innings. Next closest is San Diego's Dustin Moseley at 2.55, according to STATS LLC.

"I thought the deal was dead a few days ago . . . I called (the Mariners) back with different ideas," Dombrowski said of the deal.

Dombrowski acknowledged Mariners were good fit for Tigers because Mariners need offense. He didn't say it, but implication is other teams were asking for Jacob Turner or Andy Oliver or Rick Porcello for a starting pitcher.

CBSSports.com Danny Knobler first reported the trade this morning.

Of Fister, Dombrowski added: "His WHIP is one of the best … He gives us that solid six- or seven-inning guy who gives us a chance to win every time he takes the ball."

Pauley, 28, has appeared in 39 games with Seattle in 2011, compiling a 5-4 record and 2.15 ERA. He is tied for the lead among all American League relievers with five wins.

"David Pauley is having a very good year," Dombrowski said. "We think he's going to be somebody who is going to help stabilize our bullpen." "
